RAZOR-'BLADE-ASTROPPING DEVICE.

SPECIFICATION forming part of Letters Patent N 0. 712,385, dated October 28, 1902. Application filed May 7,1902 Serial No. 106,234. (No model.) i

To all whom it, may concern:

Be it known that we, FREDERICK KAM E RICHARD KAMPFE, and OTTO KAMPFE, citizone of the United States, residing in .New York, borough of Brooklyn, and State of New York, have invented certain new and. useful Improvements in Razor-Blade-stropping De bladeholder without impairing the back of .the holder and producing thereby'edges by which the surface of the strop is scratched olf or impaired; andfor this purpose the invention consists of a razor-blade-stropping device comprising a blade-holder for the.

blade, a handle, and a disk-shapedguard device arranged between the blade-holder and handle, said blade-holder being arranged at an obtuseangle of inclination to the axis of the handle.

The invention consists, further, of a razorblade-stropping device comprising a bladeholder, a'handle for the san1e,.said bladeholder being ar'rangedat an obtuse angle of inclination to the handle, and a swivel connection between the blade holder and handle; and the invention consists, lastly, of a razorbladestropping device in whichthe bladeholderis provided with elongated slots and filling-pieces corresponding in shape therewith and connected by a narrow shank with the body of the blade-holder, so that the proper degree of elasticity is imparted tothe jaws of the blade-holder Without cutting holes in the back of the same.

In the accompanying drawings, Figures 1,

2, and 3 are side elevatiops of our improved device for stropping razor-blades, showing Referring to the drawings, A represents a blade-holder, which is made of suitable sheet metal and provided with converging sides for engaging the blade B. The blade-holder A is connected witha handle H and is bent I at an obtuse angle of inclination to the axis of the same, and as shown in Fig. 1, the handleis attached permanently to the bladeholder and is roughened so as to be readily turned by the fingers from one side to the other when stropping the blade. The handle H is provided at its connection with the bladeholder with a disk-shaped guard O, by which the holder is guided on the edge of the strep, so that the edge of the blade is passed to and fro uniformly in one direction or the other over the strop without scratching the same. For facilitating the turning of the bladeholder on the handle, the modifications shown in Figs. 2 and 3 have the sockets. of the bladeholder connected by a swiveljoint with the handle H, and the socket A may be provided with a guard-disk C, as shown in Fig.3. The

stroppin g device shown in Figs. 2 and 3 shows the blade-holder A as arranged at an obtuse angle of inclination to the handle H and I swiveled on the pin P, which is secured rigidlyin the handle H. On the pin P is loosely secured the sleeve S, which is provided with a slightly-concave finger-piece or collar "D, secured rigidly thereto, and the upper end of the sleeve S receives the socket A of the blade-holder, and a binding-collar E retains the blade-holder A firmlyon the sleeve S, as

into the blade-holder or its removal from the same. The slits reduce the stifitness of the sides of the'blade-holder; but they are ob jectionable inasmuch as theedges of the holes are liable to scratch the face of the strop and ron to impair its smoothness. For the purpose of preventing this injury to the strop the blade-holder is punched with elongated or elliptical slits a, but without removing the metal from within the slitted portion, so as to form filling-pieces a, said pieces being retained in the opening formed by the slits a v and connected by shanks a. with the back of the blade-holder, as shown clearly in Fig. 5. In this manner the filling-pieces a fill out the space of the openings and prevent any injury to the face of the strop, while the slits still produce the required degree of elasticity for holding the blade and for inserting the same, as Well as removing it from the bladeholder.

We do not desire to claim in this application, broadly, the connection of the blade 2. A razor-blade-stropping device, consisting of a blade-holder, a handle connected with the same at an obtuse angle of inclination thereto, a swivel-joint between the handle and the blade-holder, and a'finger-piece arranged at said swivel-joint and movable with the blade-holder, substantially as set forth.

3. Arazor-blade-stropping device, consisting of a blade-holder having a socket, a handie for receiving said socket, said bladeholder being arranged at an obtuse angle of inclination to the axis of the handle, a guard disk provided at the socket of the bladeholder, and a swivel-joint between the bladeholdersocket and handle, substantially as set forth.

4. In a razor-blade-stropping device, the combination of a blade-holder provided at its back with slits forming openings, and fillingpieces in said openings connected by shanks with the back of the blade-holder, substantially as set forth.

In testimony that we claim the foregoing as our invention we have signed our names in presence of two subscribing witnesses.
